app-store_skill

Overview

This skill helps you plan and optimize App Store screenshots, captions, videos, and review responses to improve conversion and discoverability. It guides asset sequencing, visual choices, caption writing, localization, and technical sizing so your store listing communicates value quickly. Use it to prepare launches, major updates, or iterative ASO improvements.

How this skill works

The skill interviews about your app type, key selling points, target audience, and competitors to craft a screenshot storyboard and caption set. It recommends a prioritized screenshot order (hero, core feature, differentiator, secondary, trust/CTA), provides caption formulas and examples by category, and lists visual and device specifications. It also outlines when to include previews, localization needs, and competitive research steps.

When to use it

• Preparing App Store assets for a launch or update
• Improving screenshot conversion or first-impression clarity
• Writing concise, benefit-focused screenshot captions
• Planning app preview videos and localization
• Auditing competitor screenshots to differentiate visually

Best practices

• Lead with a strong hero shot that communicates the main value within the first thumbnail view
• Keep captions under eight words, start with action verbs, and match the visual exactly
• Limit fonts to two, use large headline sizes for readability on thumbnails, and maintain consistent background themes
• Use device frames when context helps; omit frames to maximize real estate for content-heavy apps
• Localize captions and any in-screenshot text for priority markets and keep videos muted-friendly with a 3-second hook

Example use cases

• Create a 5-screenshot storyboard using the 5-Screenshot Framework for a productivity app
• Generate action-oriented captions for a health app localized into Spanish and German
• Plan a 15–30 second app preview video storyboard showing core workflow and CTA
• Audit top-5 competitors’ screenshots to identify color schemes, framing, and caption patterns to differentiate
• Produce device-specific export sizes for iPhone, iPad, and macOS assets
